Hi need some help please. My question re - take off weight chart for the echo.
The take off distance factor of 1.22.
Is this factor all ready factored into the chart or are you suppose to add the 22% to the toda after calculating using the chart?
Also for future reference the info in CAO 20.7.4 below is that to be used when calculating xyz aircraft that doesnt have an australian flight manual and only a manufacturers manual or should you add the recommended factors to all calculations?
TAKE-OFF DISTANCE REQUIRED
6.1 Subject to paragraph 6.3, the take-off distance required is the distance to accelerate from a standing start with all engines operating and to achieve take-off safety speed at a height of 50 feet above the take-off surface, multiplied by the following factors:
(a) 1.15 for aeroplanes with maximum take-off weights of 2 000 kg or less;
(b) 1.25 for aeroplanes with maximum take-off weights of 3 500 kg or greater; or
(c) for aeroplanes with maximum take-off weights between 2 000 kg and 3 500 kg, a factor derived by linear interpolation between 1.15 and 1.25 according to the maximum take-off weight of the aeroplane.
thanks
